This is cause be either Optifine or Forge doing something that prevents the World class from being loaded completely. Nothing to do with us and nothing we can do about, sorry.

PS: I added code to try to load that class during startup. No idea if this would help in any way, but you may want to try the development version here: https://ci.tterrag.com/job/EnderIO-Modules/job/EnderIO-Hourly/1212/ (in about an hour).
